ABSTRACT

A shower device for a bidet shower, wherein the shower device contains at least one shower arm having a shower connection for the intimate hygiene of a user; wherein the shower arm is connected to a thermostat via a water supply line, wherein the thermostat is connected to a cold-water connection and a hot water connection and the cold water and the hot water are mixed in the thermostat to form a fluid flow of a predetermined temperature, wherein the thermostat includes a scald protection.

The invention relates to a shower device for a bidet shower. The shower device includes a thermostat. A shower device comprises at least one shower arm, which can be used to perform the intimate hygiene of a user of a bidet shower.

A bidet shower is connected to a flushing-water intake, for instance, via a pressure flushing valve, or comprises a cistern (e.g., concealed water tank or surface-mounted water tank or the like) with a flushing-water inlet connected to the flushing-water intake for introducing water into cistern and a flushing-water outlet for passing the flushing water from the cistern to a flushing area of the toilet body.

From DE 10 2012 211 655 A1 a bidet shower is known, wherein the bidet shower is connected to a cold and a hot water line, or a pressure-maintaining flow heater is used, which only heats the required water. It is further disclosed that hot and cold water can be pre-mixed in a wall or in a front-wall.

Furthermore, a bidet shower is known from CN 202248182 U, in which the water provided via the shower arm is heated electrically.

When using bidet showers without electrical connection, there is often no option for using hot water for the shower function. Often, only a cold-water connection is provided for the toilet, i.e., the provision of a heated fluid flow or water flow is not feasible.

It is the object of this invention to at least partially solve the issues indicated with reference to the prior art. In particular, a shower device is to be proposed, which can be used to provide hot water for the shower function.

A shower device having the features of claim 1 contributes to the solution of these problems. Advantageous further developments are the subject matter of the dependent claims. The features listed individually in the claims can be combined with one another in a technologically useful manner and can be supplemented by explanatory facts from the description and/or details from the figures, wherein further embodiment variants of the invention are identified.

A shower device for a bidet shower is proposed, wherein the shower device comprises at least one shower arm having a shower connection for the intimate hygiene of a user. The shower arm is connected to a thermostat via a water supply line. The thermostat is connected to a cold-water connection and a hot water connection, and the cold water and hot water are mixed in the thermostat to form a fluid flow of a predetermined temperature, wherein the thermostat includes scald protection.

In particular, the predetermined temperature-controlled fluid flow can be requested via a control unit of the shower device, at least for providing the shower function.

In particular, the shower device does not have an electrical connection.

In particular, a temperature of the fluid flow can be adjusted solely at the thermostat.

In particular, the thermostat has (solely) a first inlet for connection to the cold-water connection, (solely) a second inlet for connection to the hot water connection, and (solely) an outlet for connection to the water supply line.

In particular, the thermostat is disposed in a bidet shower or a toilet seat of a bidet shower or separate from a bidet shower.

Further proposed is a bidet shower, at least comprising

-   -   a toilet body having at least one waste-water drain (for         discharging waste water from the bidet shower into a waste-water         pipe, which can be connected to the waste-water drain) and with         a flushing-water intake for introducing flushing water into a         flushing area of the toilet body, and     -   the shower device described.

A bidet shower is connected to a flushing-water intake, for instance, via a pressure flushing valve, or comprises a cistern (e.g., concealed water tank or surface-mounted water tank or the like) with a flushing-water inlet connected to the flushing-water intake for introducing water into the cistern and a flushing-water outlet for passing the flushing water from the cistern to a flushing area of the toilet body.

In particular, the bidet shower has a cistern with a flushing-water inlet connected to the flushing-water intake (for introducing (flushing-) water from a flushing-water supply line into the cistern) and a flushing-water outlet for introducing or forwarding flushing water from the cistern into the flushing area of the toilet body.

In particular, the bidet shower has no electrical connection and only one water connection for connecting the flushing-water intake and the water supply line of the toilet shower device to the water connection. This means in particular that the thermostat is disposed upstream of the water connection and that solely the thermostat can supply flushing water to the flushing-water intake.

In particular, a control unit of the bidet shower can be used to request the pre-determined temperature-controlled fluid flow for filling the cistern or for flushing the flushing area and for providing the shower function.

In particular, near a toilet there is frequently a washbasin having a hot water connection and a cold-water connection. With the use of a thermostat, the hot water connection and the cold-water connection near a bidet shower can be used to set a maximum temperature of the fluid flow toward the bidet shower and, in particular, toward the shower arm. Hot water can thus be provided at the otherwise usual cold-water connection of a bidet shower, wherein scald protection can be guaranteed at the same time.

Scald protection can be accomplished in a thermostatic mixing faucet by limiting the discharge temperature within the faucet.

In particular, limiting the temperature of the water entering the bidet shower to below 65° C. or to below 55° C. or to below 45° C. can safely prevent undesirable severe scalding or, in the case of the specified lower temperatures, irritation of the skin.

The safety of the scald protection is additionally increased if a thermostat is used, which also has protection against pressure fluctuations and/or against a failure of the cold-water line and in this case also shuts off the hot water supply.

In particular, a maximum temperature of the fluid flow mixed in the thermostat from cold water and hot water can be reliably preset at the thermostat. In particular, the thermostat is used to set a temperature between 30 and 45° C. such that a preheated fluid stream can be provided to the user of the bidet shower for intimate hygiene via the shower arm.

In particular, the flushing of the flushing area (by introducing flushing water, from the cistern via the flushing-water outlet or from a flushing-water supply line, into the flushing area) can be requested via the control unit (of the shower device and/or the bidet shower). The filling of a cistern via the flushing-water inlet may also be linked to this request or may then be performed.

Furthermore, the shower function can be requested via the shower arm using the control unit (in a joint or separate operation).

In particular, the introduction of flushing water into the cistern via the flushing-water inlet or into the flushing area starting from a flushing-water intake can occur with a time delay to the activation of the shower function via the shower arm. In particular, if, for instance, the flushing-water intake and the shower arm can be jointly supplied with water via the thermostat, it can be ensured that no remaining water from the water supply line (and thus possibly not sufficiently heated) is supplied via the shower arm, but only water that was currently mixed by the thermostat and is thus heated.

In particular, the shower device and/or the bidet shower has/have no electrical connection (in particular not for its operation and/or for its temperature control of the water) and possibly only one water connection. The single water connection of the bidet shower can be used, in particular, for the joint connection of the flushing-water intake for flushing the flushing area and of the shower connection of the shower arm to the water connection.

In particular, a flow heater and/or electrical connection lines can be omitted by providing a temperature-controlled fluid flow through the thermostat, and by mixing hot water with cold water inside the thermostat, if required.

In particular, the space otherwise required for storing a heated water supply can be saved.

In particular, the thermostat can be disposed in the area of the shower device (e.g. in the bidet shower or in a toilet seat of the bidet shower) or separate from the shower device and the bidet shower.
